About
I started in software development. My assignments through Apside at CNAV, Harmonie Mutuelle and Banque de France gradually led me towards data integration, data quality and Business Intelligence.
I pay particular attention to reliable, maintainable processes that the teams using them can understand.
Tell me about your context, what is holding you back and the outcome you need. I can then give you an initial assessment.
